Overview

All of the pilot projects will save more water than required by the 1992 Energy Policy Act, often through the careful selection of low-flow plumbing fixtures and the planting of native, drought-resistant plants that require minimal irrigation. The seven LEED buildings save an estimated total of over 500,000 gallons per year in water, which is 43% of the water used in these buildings. Through the collection and use of rainwater and the cleansing and reuse of building wastewater, these projects altogether will save an additional one million gallons of potable water annually, relative to what is typically used for landscaping, site maintenance, and vehicle washing activities.
